Street tral'lic becai'iee oi the excavation necessary to jnrovide iorthe builiiling' of the manhole.

The main object of the present invention into provide a manholeconstructed in sections whi zh can be manufactured by cheap labor awayfrom the site of the proposed manhole and which can be 'very quicklyas-v sembled by cheap labor in the manhole excavation.

Another object of the invention resides in forming the manhole sectionsso that they can be integrally united at their joints, and therebyproduce a manhole integral from top to bottom when located in sites.`

llinother object oi" the invention is to provide each section with oneor more rungs which lorm a ladder for the manhole when the sections areassembled.

Other objects off the invention will appear as the detailedfflescription thereof proceeds.

The bottom section is preferably cylindrical, while the euperposedsections 7 and il are shaped. as hollow truncated cones. The section lcomprises an inner cylindrical plate 9 concentrically arranged withinand spaced apart trom an outer cylindrical plate l0, the space betweenthe platee 9 and l() heing filled with pitch or concrete or any othersuitable binding material, 11.

The upper end oli the plate E) le slightly oli'eet inwardly to :form anollieet bearing` l2, and the upper end of plate 10 ie oil'eet outwardlyto liorm oil'eet bearingl 13 cooperating;` with bearing.;l l2 to form aseat for the corre- :spending ond lei: of the section 7.

Parte of the offset bearings l2 and 13 are further oli'set to 'orm pourepouts l5 through which the binder ll is adapted to be poured when thesections are assembled.

'lhe joint between the sections 7 and 8 is substantially the same as thejoint between sections l and 7 and the parte thereof are similarlym'unbercd. The pour epoute l5 in ihc joint between ecrtione4 l and 'i'lie in the plane of Section and make the joint appear slightlydill'erent trom the joint between eee tions 7 and 8, "where the pourholes are shown at an angle of 9() degrees relativo to those Shown inthe lower joint. j

` It munt be uaderstoml that the elemente ot the Several sections; areassembled away from the manhole excavation and that the binder lll, inpoured into the space between er' and outer plates olf' each ocation illuch el ce troni the bottoni of the section up to thefoifsets formed toreceive ,the lower end of the next superposed .-section. then an uppersection located binder 11.

properly on the one immediately below'vit,

binder material can be poured in through pour holesV 15 to till thejoint and integrally unite thetwo sections.

The sections 7 and 8,. shaped as hollow truncated cnes,arealso made ofinner and Vouter plates 16 and 17 with the inner plate .16arrangedc'oncentrically within the plate y 17 andgspaced apart therefromto receive the binder 11.Vlr

Theiupper section 8 is finished flush at its top-edgeto'receive aman-,hole cover 18 which may, 1f'desired,`be formed oit Ytwo plates 19and 20, separated by binder 11. As shown vin the drawing, the cover 18`is provided with a flange 19 adapted to seat in a recess 21-formed in aconcrete or other suitable ring, 'and maybe removed by hooks adapted topass through holes 22 and 23 formed in the top plate oi cover 18.

f The conduits and 6 are also preferably formedby cylindrical tubes 24and 25 conc'entrieallyV arranged and bound together by .The inner tube24 has a fla-nge 26 turned out to engage the inner plate 9 et thesection land the outer tube has a flange27 formed to engage the outerplate '10 oti section 1.

`The whole construction intended to provide-'completeinsulation betweenthe inner and outer plates of the manhole and between the inner andouter tubes of conduits connected thereto. .The plates-are intended tobe made of rust proof iron and to be assembled in sections with binderbetween them beforetheir assembly in the manhole excavation. V

In order to obviate the necessity ot using ladders in kthese manholeseach section is provided with a rung 28 formed by a rod of steel orother suitable material inserted asa chord vinslots cut in the offset 12of the inner plate of each section.

In the modification shown in Figures 4, 5,

i and 6, the sections are all cylindrical, the

lower-section 29 being formed of concentrically spaced apartfplates, 32and'33 vseparated by the binder 11..

Conduite 34 and 85 snnilar tothe conduits 5 and'G are similarlyconnected to the inner and outer plates 32 and 33, respectively.

' In-order to form the joint between the scct'ions29 and 30,-the outerplate is inn wardly offset at its upper end to form a recessed portion3G and a shoulder 37 formlower section 29. The inner plate 39 of section3() tits snugly against the outer face of theinner plate 32 of the lowersection 2!) and at intervals is provided with slots 14.() adapted topermit binder to tlow between the upper and lower sections in the jointthereof when such binder is poured through the pouring olt'sets 41suitably formed Varound the inner plate 32.

,The upper section 31 is connected to the adjacent lower section 30 by asimilar joint and terminates at its upper end to form a seat for aconcrete ring 42 in which a manhole cover 13 similar to that shown inFigure 1 is adapted to seat. Each of the. sections in this modificationis provided with a rung l1-il extending across the inner plates as achord and seated in slots t5 and 4G formed in the upper edge of saidinner plates, the inner plates otl the upper section being slotted toseat over the projecting ends of said rungs and lock them in position.

The modification shown in Figures 7 and 8 is also cylindrical and thejoints between the sections L17, A18, 49 and 50 are the same as areshown in Figure 1. In this moditication, the lower sections L1-7 and 48are provided with apertures formed to receive tubular conduits 51, 52,and 51, and the inner plates of all the sections are slotted to receivethe rungs to form a ladder as in the previously described modifications.The manhole cover 56 is similar to that shown in Figure 1 and adapted tobe similarly positioned in a concrete ring 57 seated on the top of theupper section 50.

In the forms shown in Figures 9, 10 and 11, the sections arerectanguliirly shaped to form when suitably united a large vault orchamber from which conduits may extend in any desired direction. Thesesections are each composed ot separate units adapted to be bolted orriveted together. For example, t-he section 58 shown in Figure 1()comprised of end units 5t) and G() connected by flanges G1 and (S2 to acentral unit (33. Stiffening plates (it (see Figure 11) are bolted orriveted to said flanges 61 and (32 near the top and bottom of said unitin order to form struts to resist the inward pressure on the walls ofthesection.

Conduits 65 and (itlextend from the end units 58 and Gt), respectively,and are coinposed of inner and outer tubes (3T and ('8 adapted to beconnected to the inner and outer walls (S9 and 70 of each unit, binderll being poured into the spaces between spaced apart walls of saidconduits and sections, as in the other mmliiieations.

The various sections in this rectangular form of the invention areadapted to be superposed one on the other and connetded by jointssimilar to those shown in Figure 1 of the drawing, which joints areadapted to be filled through pour holes 71 suitably llo formed aroundthe outer and inner plates of the lower section. Each of the sectionsand the units thereof may be provided with ladder rangs 72 eitherriveted or otherwise secured to the opposite walls of each unit or setinto slots formed in t-he upper-edges of the inner plate of each unit;

A single cover 73 may be extended over the top unit and provided withflanges adapted to facilitate the seating thereof on the top section.lVhere a large cover used suitable manhole plates 74: 'may be formedtherein in order to 2give admission to any part ol the manhole wallwithout necessitating the raising of the whole cover 73. The severalparts of the cover may beY formed' by spaced apart plates and the spacesbetween said plates may be filled with insulartingi binder ll asdesired.

lt will be apparent from the foregoing description that I have providedmanholes and vaults which may be varied as to size and which may beformed in sections ot standard sizes adapted to be assembled veryquickly and cheaply in previously formed excavations. It will alsobeapparentthat conduits may be connected up'very quickly to any of thesections forming` part of the i'nanholcs described herein.

Vihile l have shown a conduit as entending from intermediate parts ofeach section, it is to be 'understood vthat these conduits may bereadily located at the joint between superposed sections, which may benotched to lit into each other and over any conduit positionedtherebetween with the insulating,l binder properly packed between theelement of the sections and the conduit.

What I claim is:
